FIELD OF THE INVENTION

The present invention substantially relates to the technical field of drugs, cosmetics, medical products, disinfecting products, healthcare products, food, and household chemicals, and more specifically, relates to a mussel adhesive protein product and a use thereof for inhibiting skin inflammation.

DESCRIPTION OF THE RELATED ART

As the first physiological barrier and the largest organ of human body, skin always participates in functional activities of the body, maintains the unity of opposites between the body and natural environment. Moreover, any abnormal conditions of the body could be reflected from the skin surface as well. Skin consists of epidermis, dermis and subcutaneous tissues, and comprises numerous auxiliary organs, such as follicle glands, sebaceous glands, finger nails, toe nails, blood vessels, lymphatic ducts, nerves and muscles. Skin has almost perfect capabilities of physiological protection, such as barrier function, perception function, body temperature regulation function, absorption function, secretion and excretion function, etc., and plays a very important role in maintaining the body health.

Inflammation is a defensive response by an organism to irritation, with manifestations such as redness, swelling, heat, pain, and dysfunction. In an inflammatory process, on one hand, a damage factor directly or indirectly damages tissues and cells, and on the other hand, the damage factor is diluted, killed and surrounded through inflammatory hyperemia and exudation. At the same time, the damaged tissues are repaired and healed through regeneration of parenchymal and interstitial cells. Therefore, it can be stated that inflammation is a unified process of damage and anti-damage.

Mussel adhesive protein (MAP), also known as Mytilus edulis foot protein (Mefp), is a special protein secreted by marine shellfish, such as Mytilus edulis Linnaeus, Mytilus coruscus and Perna viridis. Mussels are typically attached, in groups, to coastal reefs or ship bottom and have the ability to resist wave impacts in coastal waters. In fact, mussels can be extremely firmly attached to a base of almost any material, such as metals, wood, glass, etc. The main reason why mussels have the above characteristic is that such a special adhesive protein can be produced and stored inside the byssus gland thereof. Mussels release the adhesive protein through byssus to a surface of a solid like rock, to form a water-proof bonding and consequently fix itself.

At present, 11 adhesive protein subtypes have been identified in mussels, including mefp-1, mefp-2, mefp-3, mefp-4, mefp-5, mefp-6, the collagens pre-COL-P, pre-COL-D, pre-COL-NG, and the mussel feet matrix proteins PTMP and DTMP (Yaoyao Zhu, et al., Advances in Marine Science, 2014, 32 (4): 560-568). MAP has 2 structural characteristics: (1) comprising lysine, such that the protein carries a high loading of positive charge; (2) comprising 3,4-dihydroxyphenylalanine (DOPA, Levodopa). Human cells and tissues carry negative charges. MAP is tightly bonded to the cells and tissues through the static interaction between its own positive charge and the negative charge of the human cells and tissues, thereby playing a role of protection and treatment. In addition, DOPA is oxidized to produce o-diquinone, which may be crosslinked with unoxidized DOPA to form a membrane or a reticular support, such that the proteins are attached to human body surface in a tighter and firmer manner to play a protective role. MAP is a macromolecular protein, and it needs about 3-10 days to be completely degraded in human body. It has superior ability to be attached to cells and tissues, such that MAP is stable in a local part to continuously play its role.

Despite the above characteristics of MAP, MAP products are applied in a very limited number of fields at present. The MAP production is mainly controlled by BD Biosciences from the U.S., Kollodis from South Korea, and Biopolymer from Sweden. However, these companies' products are either directly used as an MAP solution or stored as a freeze-dried powder and dissolved prior to use. Their applications are mainly limited to micro-cellular bonding and tissue adhesive agents. There are also reports that MAP is used for fetal membrane repair, seawater corrosion-resistant coating, cardiac drug carrier, etc.

SUMMARY OF THE INVENTION

One object of the present invention is to provide MAP products.

MAP used herein refers to one or a mixture of several selected from the group consisting of 11 MAP subtypes, including mefp-1, mefp-2, mefp-3, mefp-4, mefp-5, mefp-6, the collagens pre-COL-P, pre-COL-D, pre-COL-NG, and the mussel feet matrix proteins PTMP and DTMP, that are currently known and purified from marine mussels, such as Mytilus edulis Linnaeus, Mytilus coruscus, and Perna viridis, in bivalve mollusks of Mytilidae. MAP used herein may have a pH value, in an aqueous solution, in a range of pH 1.0-7.0, and in particular, in a range of pH 3.0-6.5 for better therapeutic results thereof.

MAP used herein may be obtained using the following preparation methods, for example, a method for separating and purifying MAP by using mixed adsorption chromatography according to the Chinese Patent No. ZL200710179491.0, a method for purifying MAP by using carboxymethyl ion exchange chromatography according to the Chinese Patent No. ZL200710179492.5, and a method for separating and purifying MAP by using salting out and dialysis according to the Chinese Patent No. ZL200910087567.6.

MAP used herein may be in a form of solution or freeze-dried powder, and in particular, the MAP concentration in a product may be 0.1-15.0 mg/ml. When the concentration is overly low, MAP does not have a good effect, and when the concentration is overly high, it may cause cytotoxicity, skin irritation, etc., which is not favorable for treatment of skin inflammations.

MAP used herein may also be combined with excipients to prepare a liquid formulation. An exemplary MAP liquid formulation is prepared by dissolving or diluting an MAP stock solution or freeze-dried powder to a certain concentration or pH value, and the solution used for dissolution or dilution could be water, physiological saline, phosphate solution, acetate solution, borate solution, etc. MAP in the final product may have a pH value in a range of pH 1.0-7.0, and in particular, in a range of pH 3.0-6.5 for better therapeutic results thereof.

MAP used herein may also be combined with excipients to prepare a gel formulation. An exemplary MAP gel formulation is prepared by mixing an MAP solution or freeze-dried powder with a gel matrix material, and the gel matrix material may be one or any combination of cellulose derivatives, Carbomer and Alginates, gummi tragacanthae, gelatin, pectin, Carrageenan, gellan gum, starch, Xanthan gum, cationic guar gum, agar, noncellulosic polysaccharides, vinyl polymers, acrylic resins, polyvinyl alcohol and carboxyvinyl polymer.

MAP used herein may also be combined with excipients to prepare a lotion. An exemplary MAP lotion is made by mixing an MAP solution or freeze-dried powder with a lotion matrix, and said lotion matrix may comprise one or any combination of cellulose derivatives, glycerin, noncellulosic polysaccharides, and propanediol.

The term used herein, inhibit, refers to a process that mitigates the original damages after a tissue or organism is irritated. The term used herein, treat, refers to a process that intervenes or changes a specific health state and activities taken to relief suffering.

Skin inflammation is a skin disease and one of the common diseases and frequently-occurring diseases that severely affect human health. When the skin's barrier function is weakened, inflammations inside the skin, such as coarseness, redness, itching, eczema, and dryness, will occur, and the causes are external and internal. Internal causes involve body conditions, hormone level, pressure, etc.; external causes include, for example, UV, allergens, heat and other irritations. Only through treatments that inhibit the inflammation, can the skin condition be improved.

Small lumps, refractory ulcers, and pigmented spots caused by skin inflammation, if not treated promptly, will develop to basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. Basal cell carcinoma and squamous cell carcinoma are just some small spots with coarse surface in the beginning, which are slightly redder or whiter than surrounding skin, or may be tiny lumps or small ulcers that tend to bleed, are slow to heal, or do not heal. Early symptoms of malignant melanoma usually include the appearance of skin pigmented spots, change of mole colors, appearance of new moles, and the production of brown and black pigment cells due to pathological accumulation.

Dermatitis is a general term for skin inflammatory diseases caused by various internal and external infectious or non-infectious factors, and its causes of disease and clinical manifestations are complex and diversified. Clinically, a certain dermatitis is often defined to be a certain dermatitis according to the cause of disease, disease location or other clinical features. For example, dermatitis caused by contact with a substance is referred to as contact dermatitis, dermatitis caused by internal use of a drug is referred to as dermatitis medicamentosa, etc.

Eczema is a skin inflammatory reaction with strong itching caused by a variety of internal and external factors. It has three phases, acute, sub-acute, and chronic. In the acute phase, there is a tendency of exudation, while the chronic phase includes infiltration and hypertrophy. Some patients directly have chronic eczema. Skin lesions have characteristics such as multi-form, symmetric, itchy and easily recurring.

Skin ulcer is a common disease and frequently-occurring disease in surgery of traditional Chinese medicine, which is a topical disease with ulcers on the skin as the main clinical manifestation, inability to heal for a long period as clinical feature, and with skin tissues missing, damaged, liquefied, infected, and necrotic. As the ulcerated surface is hard to heal and costly, it causes great mental pressure and economic loss to the patients, and severely affects the body health and life quality of the patients.

Herpes refers, in a broad sense, to diseases caused by viruses in herpetoviridae. At present, it is known that eight viruses in this family could infect humans, and these viruses are collectively referred to as human herpes viruses. Among them, the common ones include varicella zoster virus, herpes simplex virus, etc., and herpes could infect a number of human organs.

Acne is a follicular (pilosebaceous unit) chronic, inflammatory skin disease, the occurrence of which is closely related to main factors like hypersteatosis, blocked pilosebaceous ducts, bacterial infection and inflammatory reaction. It tends to occur in youth, and would often naturally mitigate or heal after puberty. Clinical manifestations are characterized by multiform skin lesions on the face, such as pimple, rash, pustule, nodus, etc.

Hives is a localized edema reaction due to expansion of skin and mucosal small vessels and increased permeability, which typically subsides within 2 to 24 hours, but will recur to produce new skin rashes. The causes of hives are very complicated, and causes cannot be identified for about ¾ of the patients, in particular in the case of chronic hives. Common causes mainly include: Food and food additives; inhaled substances; infection; drugs; physical factors, such as mechanical irritation, coldness and heat, sunshine, etc.; insect bites; mental factors and endocrine changes; genetic factors, etc.

Polymorphous sunlight eruption or polymorphous light eruption is a photoallergic reaction, which is a recurrent, chronic, multiform, and photosensitive skin disease. Currently, it is believed that this might be a delayed photoallergy caused by a variety of reasons. A variety of photo-allergens are involved with this.

Early manifestations of skin cancers are mostly erythema-like skin lesions, accompanied by scaly desquamation or crust formation. It is difficult to differentiate its histological type through observation with naked eye only, and moreover, it tends to be mistaken as benign skin diseases like psoriasis, eczema. The diagnosis can be confirmed often through pathologic examination. Skin cancers have a low incidence rate in China, but are one of the common malignant tumors among white people. Basal cell carcinoma is the most common skin cancer.

Psoriasis, commonly known as serpedo, is a chronic, inflammatory skin disease with a relatively long course of disease and tendency to recur. Some patients almost never heal in their entire life. Clinical manifestations of psoriasis mainly include erythema and scales. It could occur over the whole body, more commonly seen on scalp and limb extension sides.

Burns usually refer to tissue damages caused by heat, including hot liquids (water, soup, oil, etc.), steam, high-temperature gases, flame, red-hot metal liquid or solid (e.g. melted steel, steel ingot), and the tissues mainly refer to skin and/or mucosa, and in serious cases, subcutaneous and/or submucous tissues, such as muscles, bones, joints, and even internal organs, could be damaged.

Frostbite means recurrent erythema and swelling damage on local skin caused by cold weather, and in serious cases, blisters and ulcers could appear. The course of the disease is slow, and it heals on its own when the weather becomes warm, but tends to recur.

Operative incision refers to skin damage caused by surgeries.

Bruise is an injury caused by friction due to a blunt mechanical force, with epidermis peeled off and rolled as the main manifestation. It may present with scratches, scores, percussion marks, pressing marks, pressing and scratching marks, etc.

Scar is a general term of histopathological changes to the morphology of normal skin tissues caused by various traumas, which is a necessary product from the process of repairing human body traumas. When the scar growth exceeds a certain limit, various complications will take place, e.g. destruction to the appearance, dysfunctions, movement disorders, etc., in particular in the case of scars from burning, scalding, and severe injuries.

Erythema multiforme is an acute inflammatory skin disease, which is self-limited. The rash is multiform, including erythema, papule, hive, blister, etc. The characteristic skin lesion is a target lesion, i.e. iris lesion. There are various degrees of mucosal damages, and damages to internal organs in some cases.

Post radiation therapy skin damage means skin ulceration due to radiation therapy.

Folliculitis is a suppurative inflammation due to bacterial infection of the entire hair follicle. At the beginning, red papules appear, which gradually evolve into papular pustules. They are isolated and can feel slight pain. For adults, it mostly occurs in hairy positions, and for children, it tends to occur on the head. The rashes sometimes join each other, and small bald patches could form after healing.

Pathological alopecia is hair loss caused by pathological factors, such as some mental pressures, acute or chronic contagious diseases, various skin diseases, endocrine disorder, physical or chemical factors, neural factors, nutrition factors, etc.

Seborrheic dermatitis is also referred to as seborrheic eczema, which is a chronic, papulosquamous and inflammatory skin disease that occurs at positions with a lot of sebaceous glands. The skin lesion mostly begins at the scalp, and gradually spread downwards to eyebrow, nasolabial fold, cheek, behind the ears, upper chest, intrascapular area, periumbilical area, genital area, groin, etc.

External otitis is a chronic, localized and suppurative disease of external auditory meatus skin, also referred to as localized external otitis. It occurs at the cartilage part of external auditory meatus, and is one of the common otologic diseases. External otitis is mostly caused by damages to the external auditory meatus skin as a result of ear picking or by water accumulation in the external auditory meatus during swimming or showering, such that local epidermis is softened and prone to bacterial infection.

Surprisingly, the inventors find that MAP has excellent effects on mitigating erythema, redness and swelling, edema, blisters, and bullous pemphigoid caused by various skin inflammations, inhibiting exudation of subcutaneous tissue fluid, mitigating coarse pores, and suppressing itching and pain caused by inflammations.

Surprisingly, the inventors find that MAP can be used to treat dermatitis, eczema, sunburn, polymorphous sunlight eruption, skin ulcer, burn surgery (including skin grafting), frostbite, operative incision, herpes, bruise, scar, psoriasis, erythema multiforme, post radiation therapy skin damage, skin cancer, seborrheic dermatitis, pathological alopecia (including skin grafting), regular acne, acne rosacea (i.e. brandy nose), folliculitis, hives, drug eruption, polymorphous sunlight eruption, and external otitis.

For the patients in the test group that use the MAP liquid medical device according to the present invention, the percent of successful skin grafting area in the overall skin grafting area is 89.3%±1.9%; for the patients in the control group that use physiological saline, the percent of successful skin grafting area in the overall skin grafting area is 62.4%±3.2%. It shows that MAP increases the success rate of skin grafting.

Example 25 Use of MAP Liquid Medical Device in Male-Pattern Hair Loss

Take an MAP solution, use acetic acid to adjust to pH 4.5, and obtain an MAP liquid medical device, wherein the MAP concentration is 1.0 mg/ml.

Gather 10 patients of male-pattern hair loss as diagnosed by dermatologists. The manifestations include excess sebum secretion on the scalp, partial follicular necrosis, medium hair loss, and a need to wash hair every day.

Select 3 cm² to count the number of follicles before using the product. Wash the hair, use the MAP liquid medical device above for the 1st time, 2 times per day, and for each time, evenly spray to the entire scalp, and use continuously for 90 days. Chief complaints of the 10 patients: after the 1st time use, the sebum secretion decreases, and it is no longer necessary to wash hair every day. The product has an effect on controlling the oil. After 90 days of continuous use, count the number of follicles in the selected area again, and the number of follicles is increased by 35%±2.3%.

It shows that the MAP product can, on one hand, inhibit the excess sebum secretion in male-pattern hair loss, and on the other hand, repair dying follicles and treat hair loss.
